I've made a thread about this before but no one replied and it still won't launch... I don't know what's wrong. I've tried reinstalling Steam itself and I have reinstalled The Binding of Isaac many times, I have tried verifying the cache, defragmenting it but it's not working. Nothing it working. Please, someone help me I REALLY REALLY want to play this game. I don't want to buy it and then put it to waste. :\

Everytime I try to start the game up, it says 'Preparing to launch The Binding of Isaac...', it then disappears and then 'Isaac.exe' runs in the task manager but instantly closes, nothing pops up(game/error messages).

Are there some sort of hidden files I need to delete to completely remove the game or something?

Oh yes, I apologize for that. What I meant is that it did not help me. XD I'm sorry.

I deleted steam_appid.txt and I have scanned my computer for viruses; there were none. The MD5 of both the executable files are both correct. I don't know what else is wrong, thank you for helping though. I don't think I will get it to launch unless I reformat my computer which I really do not want to do, but thank you for your post. Your help is very much appreciated.
